Description

Technical Field

[0001] This utility model belongs to the field of monorail vehicle technology, specifically relating to a production line device for dismantling monorail vehicle running wheels, which is mainly used for the maintenance and dismantling of monorail vehicle running wheels. Background Technology

[0002] Monorail vehicles, as a type of medium-capacity rail transit vehicle, are being researched and applied extensively in my country.

[0003] The safety of monorail running wheels has received widespread attention within the industry. Monorail running wheels consist of tires, a support structure, rims, and spokes, such as... Figure 1 As shown, regular maintenance work is required, including replacing tire skins and spokes.

[0004] When maintaining the running wheels of a monorail vehicle, the air in the running wheel to be disassembled is first released, and then the bolts, spokes, rims, and support body are removed, thus disassembling the entire tire.

[0005] In the above-mentioned disassembly and production process of monorail vehicle running wheels, the current method used is simple tooling and manual use of jacks to disassemble the spokes and rims. During disassembly, the tire positioning is not accurate, and the spokes and rims are subjected to uneven force, resulting in quality problems such as bumps and scratches on the support and rims. Moreover, disassembly requires multiple people to complete the operation, resulting in low production efficiency and high labor intensity for operators.

[0006] Therefore, in response to these issues, and taking into account the product structure of tires, a production line device for disassembling and assembling monorail vehicle running wheels was designed and manufactured to meet the positioning requirements and improve quality during running wheel disassembly, while reducing the labor intensity of operators and increasing production efficiency. Summary of the Invention

[0007] The technical problems to be solved by this utility model are as follows: (1) Solving the problem of inaccurate product positioning during tire disassembly; (2) Solving the problem of uneven force during tire skin, spokes and rim disassembly, causing the spokes, rims and supports to be bumped and scratched, thus improving product quality; (3) Solving the problem of low tire disassembly efficiency, thus reducing the labor intensity of operators.

[0008] In view of the above-mentioned problems in the prior art, the purpose of this utility model is to provide a production line device for disassembling monorail vehicle running wheels.

[0009] To achieve the above or other objectives, the technical solution of this utility model is as follows: A production line device for dismantling monorail vehicle running wheels includes a control mechanism and a feeding mechanism, a bolt dismantling station, a spoke dismantling station, a tilting mechanism, a rim dismantling station, and a discharge mechanism, all connected to the control mechanism. The feeding mechanism and the discharge mechanism are symmetrically arranged to feed and discharge the running wheels, respectively. The bolt dismantling station is located between the feeding mechanism and the spoke dismantling station, and is used to dismantle the connecting nuts between the rim and spokes of the running wheel. The spoke dismantling station and the rim dismantling station dismantle the spokes and the rim, respectively. A tilting mechanism is provided between the spoke dismantling station and the rim dismantling station to achieve a 180° tilt of the running wheel.

[0010] Furthermore, the bolt removal station includes a nut removal work platform and a rim positioning fixture and a lifting cylinder set on the nut removal platform. The rim positioning fixture is located at the center of the nut removal work platform and includes a chamfered disc-shaped positioning block and an air jack. The disc-shaped positioning block is inserted into the center hole of the spoke plate, and the air jack is connected to the head of the lifting cylinder.

[0011] Furthermore, the control structure of the lifting cylinder is connected to the control mechanism; several universal balls are installed around the center of the nut disassembly platform.

[0012] Furthermore, the spoke disassembly station includes a spoke disassembly work platform, a pressing hydraulic cylinder, and a spoke receiving platform; a pressing hydraulic cylinder is mounted above the spoke disassembly work platform, with the pressure head of the pressing hydraulic cylinder pointing downwards and directly facing the center of the spoke disassembly work platform; a center hole is suspended at the center of the spoke disassembly work platform, and the size of the center hole is larger than the size of the spoke; an extendable spoke receiving platform is provided below the spoke disassembly work platform.

[0013] Furthermore, the spoke receiving platform is equipped with a pneumatic control structure, which is connected to the control mechanism.

[0014] Furthermore, the flipping mechanism includes a base, a flipping hydraulic cylinder, and a receiving structure. The receiving structure is set on the base and is configured as a U-shaped structure. The flipping hydraulic cylinder is set below the base and is connected to the receiving structure, causing the receiving structure to flip 180°.

[0015] Furthermore, in the initial position of the receiving structure, the opening of the U-shaped structure of the receiving structure faces the previous station—the spoke disassembly station. After being rotated 180°, the opening of the U-shaped structure faces the next station—the rim disassembly station. Rollers are provided on both long sides of the U-shaped structure.

[0016] Furthermore, the rim disassembly station includes a rim disassembly working platform, a hydraulic cylinder head, and a rim receiving platform; the hydraulic cylinder head is mounted above the rim disassembly working platform, with the hydraulic cylinder head pointing downwards and facing the center of the rim disassembly working platform; a center hole is suspended at the center of the rim disassembly working platform, and the size of the center hole is larger than the size of the rim; the rim receiving platform is located below the rim disassembly working platform.

[0017] Furthermore, the rim receiving platform is equipped with a pneumatic control structure, which is connected to the control mechanism.

[0018] Furthermore, the feeding mechanism includes a feeding platform, a first tilting cylinder, and a roller conveying structure.

One open end of the discharge platform is connected to the telescopic end of the second tilting cylinder, and the fixed end of the second tilting cylinder is fixed to the rim disassembly station. A roller structure is provided on one long side of the discharge platform.

[0019] This utility model has the following advantages: (1) The device of this utility model can be accurately positioned when disassembling the connecting nut between the spoke plate E and the rim D, and the tire will not wobble and cause thread damage when disassembling the connecting nut; (2) By using the device of this utility model, the problem of uneven force on the spokes, rims and supports caused by the original manual disassembly using jacks is solved, which causes the spokes, rims and supports to be bumped and scratched, thus improving product quality; (3) Using the device of this utility model, each process is continuous during the disassembly process, and single-piece flow operation is carried out; (4) By using this utility model device, the number of operators is reduced, production efficiency is improved, and the labor intensity of operators is reduced (originally, manual disassembly required 2 people, but now the disassembly production line has reduced it to 1 person to complete all disassembly processes), thus saving labor costs.

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. Example 1:

[0023] Reference Figure 2 As shown, the monorail vehicle running wheel disassembly production line device of this embodiment includes, in sequence, a feeding mechanism 1, a bolt disassembly station 2, a spoke disassembly station 3, a turning mechanism 4, a wheel rim disassembly station 5, and a discharge mechanism 6.

[0024] The feeding mechanism 1 includes a feeding platform 11, a first tilting cylinder 12, and a roller conveying structure 13. The feeding platform 11 is U-shaped and houses the traveling wheels A. One open end of the feeding platform 11 is connected to the telescopic end of the first tilting cylinder 12, and the fixed end of the first tilting cylinder 12 is fixed to the bolt removal station 2. The telescopic movement of the first tilting cylinder 12 drives the feeding platform 11 from a horizontal to a vertical position. A roller conveying structure 13 (without power) is installed on one long side of the feeding platform 11 (this long side is located at the bottom when the feeding platform 11 is placed horizontally). When the feeding platform 11 is in a vertical position, push the traveling wheel A into the feeding platform 11. At this time, the first tilting cylinder 12 extends, pushing the feeding platform 11 to tilt to a horizontal position and then stopping (e.g.). Figure 3 As shown), the traveling wheel A enters the next station (bolt removal station 2) through the roller conveyor structure 13.

[0025] Among them, such as Figure 4 and Figure 5 As shown, the bolt removal station 2 includes a nut removal work platform 21, a rim positioning fixture 22, and a lifting cylinder 23. The nut removal work platform 21 serves as a base and is equipped with the rim positioning fixture 22 and the lifting cylinder 23. The rim positioning fixture 22 is located at the center of the nut removal work platform 21 (e.g., ...). Figure 5 As shown), it includes a chamfered disc-shaped positioning block and an air jack. The disc-shaped positioning block is inserted into the center hole of the spoke plate E to prevent the entire running wheel A from shaking when the nut is removed.

[0026] The lifting cylinder 23 rises upward and connects to the aforementioned air top.

[0027] Because the spokes E of the traveling wheel A are fastened to the rim D with 24 sets of bolts and nuts, the connecting nuts need to be loosened and removed at this bolt removal station 2. The traveling wheel A to be disassembled is transferred to the nut removal work platform 21 at this station via the upper roller conveyor structure 13 of the production line. Several universal balls are installed on the nut removal work platform 21, and the traveling wheel A can be quickly moved to the disassembly position on the universal balls. The head of the lifting cylinder 23 has a contour tool (i.e., the rim positioning tool 22), which is inserted into the center hole of the spoke E for positioning. At this time, the connecting nuts between the rim D and the spoke E can be loosened with a pneumatic wrench to complete the disassembly of the nuts.

[0028] Among them, such as Figure 6 and Figure 7As shown, the spoke removal station 3 includes a spoke removal work platform 31, a hydraulic cylinder 32, and a spoke receiving platform 33. The hydraulic cylinder 32 is mounted above the spoke removal work platform 31, with its pressure head pointing downwards towards the center of the work platform 31. A central hole, larger than the size of the spoke E, is suspended at the center of the work platform 31 to facilitate the removal of the spoke E. The spoke receiving platform 33 is located below the work platform 31. Preferably, the spoke receiving platform 33 is equipped with a pneumatic control structure to facilitate its extension from below the work platform 31.

[0029] Move the aforementioned traveling wheel A to the center position of the spoke removal station 3, and operate the hydraulic control structure to lower the pressure head of the downward hydraulic cylinder 32 until it contacts the spoke E. Use the thrust of the downward hydraulic cylinder 32 until the spoke E is completely detached from the rim D. Below the spoke removal work platform 31 is an accessible spoke receiving platform 33. After the spoke E is detached from the rim D, it falls into the spoke receiving platform 33 through the center hole of the spoke removal work platform 31. Operate the pneumatic control structure of the spoke receiving platform 33 to extend the spoke receiving platform 33, and the operator can remove the spoke E.

[0030] Among them, such as Figure 8 and Figure 9 As shown, the flipping mechanism 4 includes a base 41, a flipping hydraulic cylinder 42, and a receiving structure 43. The receiving structure 43 is set on the base 41. The receiving structure 43 is a U-shaped structure with rollers on both long sides (in the initial position of the receiving structure 43, the opening of the U-shaped structure faces the previous station - the spoke disassembly station 3. After flipping 180°, the opening of the U-shaped structure faces the next station - the rim disassembly station 5). The flipping hydraulic cylinder 42 is set below the base 41. The flipping hydraulic cylinder 42 is connected to the receiving structure 43 and can make the receiving structure 43 flip 180°.

[0031] The initial position of the receiving structure 43 is connected to the spoke removal station 3. The traveling wheel A (with spoke E removed) moves from the spoke removal station 3 onto the receiving structure 43. The hydraulic control structure is operated, and the tilting hydraulic cylinder 42 is activated, causing the receiving structure 43 to tilt 180°, so that the small end of the rim D faces upward, allowing the traveling wheel A (with spoke E removed) to enter the next station (rim removal station 5). The hydraulic control structure is operated again to return the receiving structure 43 to its initial position.

[0032] The rim disassembly station 5 operates on the same principle as the spoke disassembly station 3, but the size of the hydraulic cylinder head is different. For example... Figure 10 and Figure 11As shown, the wheel rim disassembly station 5 includes a wheel rim disassembly working platform 51, a hydraulic cylinder head 52, and a wheel rim receiving platform 53. The hydraulic cylinder head 52 is mounted above the wheel rim disassembly working platform 51, pointing downwards towards the center of the platform. A central hole, larger than the wheel rim D, is suspended at the center of the wheel rim disassembly working platform 51 to facilitate the removal of the wheel rim D. The wheel rim receiving platform 53 is located below the wheel rim disassembly working platform 51. Preferably, the wheel rim receiving platform 53 is equipped with a pneumatic control structure to facilitate the extension of the wheel rim D from below the wheel rim disassembly working platform 51.

[0033] Move the traveling wheel A (with spoke E removed) to the center of the rim removal station 5. Operate the hydraulic control mechanism to lower the hydraulic cylinder head 52 until it contacts the small end of the rim D, until the rim D detaches from the tire A. Below the rim removal work platform 51 is an accessible rim receiving platform 53. After the rim D detaches from the tire A, it falls into the rim receiving platform 53 through the center hole of the platform. Operate the pneumatic control mechanism of the rim receiving platform 53 to extend it, allowing the operator to remove the rim D.

[0034] The discharge mechanism 6 has the same structural principle as the feeding mechanism 1, but the number of rollers differs. For example... Figure 12 As shown, the discharge mechanism 6 includes a discharge platform 61, a second tilting cylinder 62, and a roller structure 63. The discharge platform 61 is U-shaped and is used to house the traveling wheel A (the rim D and spoke E have been removed). One open end of the discharge platform 61 is connected to the telescopic end of the second tilting cylinder 62, and the fixed end of the second tilting cylinder 62 is fixed to the rim disassembly station 5. The extension and retraction of the second tilting cylinder 62 drives the discharge platform 61 from a horizontal state to a vertical state. A roller structure 63 (a non-powered roller) is installed on one long side of the discharge platform 61 (this long side is located on the bottom surface when the discharge platform 61 is placed horizontally). When the discharge platform 61 is in a horizontal state, push the traveling wheel A (with the rim D and spoke E removed) into the discharge platform 61; the second tilting cylinder 62 extends and pushes the discharge platform 61 to a vertical position and then stops, and the operator pushes out the traveling wheel A (with the rim D and spoke E removed).

[0035] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model. Technologies not covered by this utility model can be implemented by existing technologies.
